Title: Optical fiber
Inventor: FUKUZAWA TAKASHI
IPC: G02B6/44
Filed: 1989-07-19
Abstract: PURPOSE:To facilitate terminal machining operation and to increase the strength and reliability of a terminal part by applying and curing a resin compound which has specific hardness at room temperature after being cured in contact with the surface of an optical glass fiber whose numerical aperture (NA) is >=0.35. CONSTITUTION:The optical fiber element 1 is constituted by forming the primary jacket layer 3 of uniform-thickness hard resin in contact with the surface of an optical transmission fiber 2 (bare wire) composed of a core 2A of multi- component glass and a clad 2B and the numerical aperture (NA) of the optical transmission fiber 2 is >=0.35. Further, the jacket layer 3 is formed by applying and curing the resin compound which has >=65 Shore hardness of JIS standard at room temperature after being cured in contact with the surface of the glass fiber 1. Thus the jacket layer 3 has the sufficient hardness to increase the external diameter size accuracy, so the jacket need not be peeled off at the time of terminal work and the optical fiber element wire 1 can be pressed and coupled with a component such as a connector as it is, so the terminal machining operation is facilitated.

Title: Cassette
Inventor: HASUDA SHUJI
IPC: G03C3/00
Filed: 1987-07-28
Abstract: PURPOSE:To exactly transfer one frame of a film and to prevent the generation of a phenomenon which makes a film in a jammed state, by providing a controlling means capable of controlling the rotation of a sprocket positioned at a winding side in the titled cassette. CONSTITUTION:The titled cassette is equipped with the controlling means in which the sprocket provided at the winding side, does not freely rotated, but is pressed to the bottom surface 4a of a casing body 4 positioned at the winding side by means of for example, an elastic spring 39, thereby increasing resistance force against the rotation of the sprocket 37. Thus, the running of a film is carried out by intermittent running of a driving shaft interposed in said sprocket 37, however, the inverse inertial force generated at the time of stopping the driving shaft, etc., is absorbed by the controlling means, and does not appear in appearance, thereby exactly carrying out the intermittent running of the film. The phenomenon which makes the film in the jammed state does not generate between the sprocket 37 and a spool 17 which are positioned at the winding side, and the winding property of the film makes satisfactorily and the trouble of injuring the film does not occur.
